por Do you know what end-to-end encryption is? The instant messaging communications They used to be an unsafe place to send sensitive information. Previously, messages could be easily read, in the absence of a security system that allowed data to be sent secretly and reliably. As a solution to this system, the cryptography technique that we will explain to you in this post emerged.
Next, we will talk about what is end to end encryption, the most effective information encryption method to protect communications between users. Currently, it is the most used to keep the signal of video calls, chats and text messages private, among others.
What is end-to-end encryption?
Instant messaging services are constantly developing, because they are one of the most used for the exchange of information between web users. End-to-end encryption is a method of encrypting datain such a way that not even the employees of the company that provides the communications service can access them.
End-to-end encryption does not use a centralized server to decrypt the information. On the contrary, the information leaves the sender’s device encrypted and reaches the receiver in such a way that the latter’s machine is responsible for deciphering the code. Thus, man-in-the-middle attacks are avoided and a secure signal between users is guaranteed.
Although its name indicates that encryption occurs «end-to-end», communication of this type can occur between two or more users. This type of encryption system has become the main standard for video calling, text messaging and chat services. Companies such as Facebook, Zoom or Skype, among others, are recognized for applying the concept of end-to-end encryption to ensure reliable data encryption.
Sending and receiving data has never been as secure as it is now, thanks to end-to-end encryption ensuring confidentiality. However, in hacking, by nature, there are always ways to break barriers and cybersecurity schemes. The simplest method to bypass end-to-end data encryption would be to gain full access to the user’s device. Otherwise, the advantage of end-to-end encryption is that it is impossible to read the information by means of signal interception.
How does end-to-end encryption work?
Now that you know what end-to-end encryption is and why it is the most secure system for encrypting information in a messaging application, let’s take a brief look how this method works and how he accomplishes his task.
To encrypt data end-to-end, the sender’s device encrypts the information using the public key of the receiver’s device, which will then decrypt the message using its Secret password and vice versa.
